What happens if you use bigger knitting needles?
Also, how does needle size affect knitting?
The size of the needle affects how big your stitches, and thus your finished product, will be. The concept of gauge, or how many stitches fit into 1 inch of knitting, relies heavily on the size of the needles. Usually, larger needles will produce a larger gauge.

Since the bigger needles make larger stitches and rows you don't need as many stitches as you do with the small needles and end up using less yarn for the same measurement. If you use the same number of stitches with the big needles as the smaller ones, you'll use more yarn, but will end up with something a lot larger.
